[Wicket-user] Conditionally updating model

2005-11-26 Thread Nick Heudecker 
Hi,

I have an edit user page that allows the admin to update various
details for a user, like email address, name, etc.  The admin can also
change the password for a user, but I want to make that optional, like
the password is only updated if the admin actually types a new
password, otherwise the User object backing the Form isn't updated
with a blank password.

Is there a suggested way to go about this? Do I end up overriding
getModelValue() or setModelValue()?

Thanks for your time.

There are a bunch of ways to do it, but I think the easiest way is to override getInput() and return null if you do not want the model updated with this component's value.For example,public String getValue() {
 String val = super.getValue(); if (val != null  val.trim().equals()) return null; return val;}--AndrewOn 11/26/05,

Or you could make your models a lit more intelligent, making it
independent of the components. Both are good.

 Should be:

 public String getInput() {
  String val = super.getInput();
  if (val != null  val.trim().equals())
return null;

  return val;
 }

I must've been staring at code too much to think of that.  Thanks.
